over on TMP there are lovely photos of Minairons 20mm motorcyclist, I have borrowed a couple of photos (below) from this ad at http://theminiaturespage.com/news/?id=478223603
where it says:
"I'm happy to share with you our upcoming set of 1:72 scale SCW figures, consisting of two Republican dispatch riders along with their Harley-Davidson motorcycles. Unlike their 1:100 scale counterpart shown below (where bike, rider and stand were cast in a single piece, with only handlebar and arms apart), this new 1:72 scale version has separate motorcycles, figures, handlebars and stands (so allowing multiple customization chances)."
